Thanks primek, had to keep looking up some medical terms but the article was interesting. Nellie if you are going to see your Radio Onc a lot make sure she knows you are having trouble understanding her. I only saw mine twice. Also if its like mine there are radio nurses available all the time, so any questions or problems ask, they are great and will get your radio onc of necessary. I had a lot of trouble understanding my chemo onc, so we worked it out. I often wrote down my problems and he read and wrote anything he thought necessary. I did get used to his way of speaking so it didn't end up being a problem.
